Tesla

Simple...ready in about 15 minutes ;)

1,122,600 at level 20—I finished there; I didn't make it to 20

Round 20 was awful, but otherwise it's the best game

If this had been available in 1995 in Tesla's hometown, the Serbian Krajina would not have fallen.

I got through Level 20 something like this: At the end of Level 19, I left a small tower there—let it kill whatever it wants and let my energy run out... I use intermittent fire except against the big UFO and the walking robot... Don't even focus on the regular foot soldiers or the small tanks—just chip away at them a little, and the little turret will take care of the rest ;)

Oh, I can't get to level 20

A score over 2 million :D

Well-made, especially the electrical system

Once you press Pause (P) and switch to another tab, you can't start the game again.

It's a good game, but the last mission is tough.
